The funding, provided to Boeing subsidiary Argon ST, covers seven systems over 18 months, representing the third lot of full-rate production units. Argon has delivered a combined total of more than 80 SSEE systems since 2000.

Argon ST is the prime contractor to the U.S. Navy for providing signals intelligence (SIGINT) systems through the ship's (SSEE) program. The SSEE Increment E (SSEE-E) program developed a tactical cryptologic system (TCS) which performs all signal processing functions necessary to acquire, identify, locate and analyze signals for external and internal information. The SSEE program supports the warfighters with actionable intelligence and provides horizontal intelligence integration across all available sources.
